AMINOPYRIMIDINONES AND THEIR PRODUCTION.

Abstract

This invention provides a process for the preparation of pyrimidinone compounds with a group R2CH(OH)- at the 5-position thereof, wherein R2 is an optionally substituted acid-stable 5- or 6-membered nitrogen-containing heteroaryl group. The pyrimidinone ring is further substituted by a side-chain of a H1-antagonist or H2-antagonist or a precursor thereof. The compounds are convertible to 5-heteroaryl methyl compounds which are either useful H1- or H2-antagonists or precursors thereof.
